/* MAP
 * Direction [directii 50297-A, adapted]: cold blue-black base (light: cold near-white), accent family fixed by the brief
 *   (violet to cyan gradient, used only on the hero word, primary buttons and step numbers), geometric system sans,
 *   large title scale, visible precise grid with cells of different sizes, the order form owns the first screen.
 *   Why: an engineering studio that sells "evidence first" should look measured: rulers, coordinates, thin borders.
 *   Own graphic element: the measured grid (hairline background grid plus mono coordinates on every section).
 * §1 tokens: dark base, light by system or toggle
 * §2 base elements, type, links, focus
 * §3 layout: container, sections, grid backdrop
 * §4 header, navigation, theme toggle
 * §5 buttons, fields, forms (order form, lead form, states)
 * §6 cards, bento, lists, tags, steps, ladder
 * §7 page parts: hero, page head, FAQ, CTA band, prose, footer
 * §8 motion and reduced motion
 * §9 responsive
